SFP Transceiver Slots
Several of the AT-9400 Switches feature slots for optional Gigabit
Ethernet SFP transceivers for interconnecting network devices over large
distances using fiber optic cable. With the exception of the AT-9408LC/SP
Switch, each SFP slot is paired with a twisted pair port. A link on an SFP
transceiver takes priority in the event both an SFP transceiver and its
paired twisted pair port have established links to their respective end
nodes. For further information, refer to “Redundant Twisted Pair Ports” on
page 32.
